The specifications listed below are referenced in whole or in part by
the Linux Standard Base. Such references may be normative or
non-normative; a reference to specification shall only be considered
normative if it is explicitly cited as such. The LSB
may make normative references to a portion of these
specifications (that is, to define a specific function or group of
functions); in such cases, only the explicitly referenced portion of
the specification is to be considered normative.
